We just closed on this house and are looking at paint colors to brighten the space. The wall with the windows is two stories facing a loft. I'm using a warm white to try to brighten the space but would like to use a blue or green on the window wall. Currently it is painted with a grayish green. The green and blue I chose are just too bright. the blue is Kingston Aqua from PPG but looks almost neon blue on the wall. The green is sage, but light, and looks like custard yellow.

I want the space to feel inviting but also light and airy. We are not fans of yellows/orange/red in our spaces. We prefer light blues and greens, to mimic the outdoors almost.

Any direction on the shades of blue or green that we should be looking at to work best with north facing light? My go to shades are not working.
